Mid century vintage Kidde Cardox C5A carbon dioxide(co2) fire extinguisher with horn. This fire extinguisher is from the 1950s as the address on the cylinder label is Chicago 11. It still has the paper maintenance tag with the date that it was last inspected / recharged as 1970

It stands about 17" high and 5" across the cylinder.

This came to us empty and that's how it's being sold and shipped. It looks online like you can get these inspected and recharged for about $30 if you still want to use it as a fire extinguisher.
